commercial applications. For F-450 and F-550 trucks operated at or near maximum Gross Vehicle Weights, the rear axle
lubricant should be replaced every 50,000 miles (80,000 km). In addition, this 50,000 mile (80,000 km) schedule should

Biodiesel
❑Biodiesel may be blended with petroleum-based diesel fuel. Such biodiesel blends are designated as BXX, where XX repre-
sents the percentage of pure biodiesel contained within the blend (e.g., B5, B20, and B100). To maintain the desired level
of performance and longevity of the engine, vehicles using biodiesel up to and including B5 should change the engine oil
and filter every 5,000 miles (8,000 km) or 200 hours of engine operation (whichever comes first).
